Heidi Hammel Quotes

We should be ready to reach out beyond our planet and beyond our solar system to find out what is really going on out there.

Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future.

Just speaking for myself, I think the return of people to the Moon has a lot to offer for understanding the formation and evolution of terrestrial worlds; so would the exploration of near-Earth asteroids by people.

We go to learn about our solar system, to search for life, and to understand what happened to Mars so we avoid it ourselves.

As far as I'm concerned, Enceladus has become the go-to place in our solar system for issues bearing on extraterrestrial life. It's a great place to examine extraterrestrial organic chemistry that is water-based and, therefore, like biotic chemistry on Earth.

We've explored every type of environment in the solar system at least once.

Titan is the one place in our solar system whose geographical and atmospheric diversity and complexity are rivaled only by the Earth's. It's very Earth-like, but it's also very different, which means we have a lot to learn as well as a prayer of understanding what we find.

There's water on Mars, and there's life beyond Brussels.

I do a lot of work with NASA and am involved in research projects studying planetary evolution, Earth-like planets, and potential conditions for life elsewhere.

I hope that by 2050 the entire solar system will have been explored and mapped by flotillas of tiny robotic craft.

Life is extremely resilient once it takes hold, but it requires rich chemistry, large energy sources, and stability, right from the beginning. The comparative planetology of our solar system makes it seem like those initial conditions are hard to come by.

Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. By exploring and understanding Mars, we may gain key insights into the past and future of our own world.

Pascal Lee is a true pioneer of Mars exploration.

A time will come when men will stretch out their eyes. They should see planets like our Earth.

For the new century, back to the moon, back to the future and this time back to stay. And then a journey into tomorrow, a journey to another planet, a manned mission to Mars.

We do have, and will continue to have an unquenchable curiosity to understand our Solar System.

We had 83 different space research projects on my last space flight in '98, and they covered the whole gamut.

I'd love to go into space again if there were a mission to Mars. I'd also love to go to a completely different planetary system, out of our solar system.

This is what the Mars Science Laboratory (MSL) represents. Experimental, explorational science. Learning about Mars as a new world. Discovering new things that will tell us about the history of our solar system, help reveal the secrets of life, and continue blazing the trail that may someday be traveled by the rest of us.

The Cassini mission was all about a comprehensive investigation of Saturn and everything in the Saturn system, and it's been a mission that's been done jointly with the Europeans.

Life outside of Earth is probably going to be really hard to find.

Among the plausible niches for extraterrestrial life in our solar system, the clouds of Venus are among the most accessible and the least well explained.

The geysering on Enceladus is the most astonishing phenomenon we have in our solar system.

There are other planets besides the Earth and Mars. I'd like to remind you that studying Venus is vital to understanding life elsewhere.

New Horizons isn't just visiting Pluto; it's visiting this entire region. Whatever it finds, this will be a signal moment for planetary exploration - the capstone to our first reconnaissance of the planets of our solar system.
